Sorry, I din understand your query on first look through. Like Jagat said, you may need to go with a temp table for this.
Do a hadoop fs -cp ../../a.* <destn dir> Create a external table with location as 'destn dir'. CREATE EXERNAL TABLE <tmp tble name> LIKE <src table name> LOCATION '' ; NB: I just gave the syntax from memory. please check the syntax in hive user guide.

ADD PARTITION' . Partitions are not retrieved implicitly into hive tabe even if you have a proper sub dir structure. Similarly if you don't need a particular partition on your table permanently you can always delete them using the alter table command. If you are intending to use a particular partition alone in your query no need to alter the partitions. Just append a where clause to the query that has scope only on the required partitions. Hope this helps.

For example I have the following directory structure data/dd=2012-12-31/a1.txt data/dd=2012-12-31/a2.txt data/dd=2012-12-31/a3.txt data/dd=2012-12-31/a4.txt data/dd=2012-12-31/b1.txt data/dd=2012-12-31/b2.txt data/dd=2012-12-31/b2.txt Is it possible to add 2012-12-31 as a partition and tell hive to load only the a* files to the table? Thanks,
